Product Overview
High-density gypsum coreboard, measuring 3000 × 600mm, developed as the core layer for Knauf Shaftwall and other multi-board fire-rated systems.
The square edge design ensures precise, close-fitting joints, maintaining the integrity of complex wall build-ups.
Each sheet covers 1.8m² and weighs 29.52kg, providing a durable and dimensionally stable solution for demanding shaftwall and service riser applications.
Faced with an ivory paper liner, the board is intended for concealed use within layered systems, where its density enhances both fire performance and acoustic separation.
A thermal conductivity of 0.19 W/mK enables its inclusion within system U-value calculations, supporting regulatory compliance.
Features & Benefits
- High-density gypsum core: Improves fire resistance and acoustic performance.
- Square edge finish: Allows tight board joints for accurate system build-up.
- Thermal conductivity 0.19W/mK: Contributes to overall thermal performance of wall systems.
- Weight 29.52kg per sheet: Ensures stability within multi-layer assemblies while remaining manageable for handling.
- Ivory paper liner: Provides a consistent surface for concealed installation.
- Board size 3000mm x 600mm: Suitable for vertical shaftwall use and reduces cutting waste.
- Thickness 19mm: Ensures durability and performance within shaftwall and fire-rated systems.
